Exceptional Expertise
USR Drilling Services is the oil and gas industry's sole and exclusive service provider of Ultra Short Radius Drilling (USRD) and Completion Technologies. The management, drilling and engineering personnel possess, on average, more than 20 years of experience with USRD. This experience began in the late 1980s with the early development and testing of the initial prototype tools.

Our expertise is the re-entry of existing wellbores to exploit bypassed reserves in mature fields. We deploy proprietary well-intervention technologies that were specifically designed to exploit remaining reserves, increase production from marginal wells, restore production from shut-in wells, and reduce water production.

We are a directional drilling company that specializes in Ultra Short Radius (USR) and Short Radius (SR) projects. The company's focus is on the market segment requiring a radius of curvature (27-60 ft.) and a slim hole (3 7/8 in. to 4 3/4 in.).

Following the mobilization for United Energy Pakistan Limited in November 2012, 8 wells were completed in three different fields from the same Block with TD reached on the 8th well on June 2013. The objective for all eight wells was to re-enter existing wells and drill USR sidetracks to increase oil production by targeting bypassed oil.

Drilling of the 13th USR well has commenced for Perenco. The first well in the campaign began in Q4 2011 and was followed by twelve consecutive wells in four different fields and from three different types of light workover rigs and 1 heavy rig. USR well applications have included re-entry sidetracks from existing wells and the drilling of USR sidetracks from three newly drilled slant wells in one field. Some of the well objectives are:

to improve field recovery

to improve PI in existing vertical wells with low mobility oil

to prove production from horizontal drain holes against water piercing tendency in vertical wells

to reduce water coning and, or fingering effect with reduced drawdown in a horizontal drain as compared to vertical well

to increase connectivity between the new horizontal wellbore to un-drained fracture networks

to access to sweet spots a few meters from the vertical wellbore by combining the USR wells with the nature of the reservoir

to support the technology in re-entering very high water cut wells in the field

to increase net reservoir length in the flank area with less number of wells

A new Work Order for additional 2 years, 2 crews was executed in November 2013. A second crew will be mobilized Q1 2014.

NEW WORLD RECORDS SET IN HORIZONTAL WELL DRILLED WITH ULTRA SHORT RADIUS DRILLING (USR) TECHNOLOGY.
Perenco Gabon SA. well OLD-10ST USR has set new world records for the longest USR horizontal section length of 430m and the largest reach-to-radius ratio of 32:1 for a horizontal well. The well was drilled in a particularly cost-competitive environment, using a small-footprint, trailer-mounted service rig. Initial production results are very encouraging and full benefits are expected from long-term behavior of horizontal drains in a reservoir with low-mobility oil and a strong aquifer drive.
